CHAIR ATTACHMENT.

Specification of Letters Patent.

To all whom it nuw concern:

Be it known that I, ALBERT THOMPSON, a citizen of the United States,residing at Fullerton, in the county of Nance and State of Nebraska,have invented new and useful i Improvements in Chair Attachments, of

"which the following is a specification.

This invention relates to chair attachmerits; and the object thereof isto provide means in a manner as hereinafter set forth for hinging, asWell as detachably connecting, an arm rest or desk to a chair arm.

Further objects of the invention are to provide an arm rest or deskattachment for chairs which shall be simple in its construction, strong,durable, adjustable, efficient in its use, readily set up, allowing forthe arm rest or desk to depend at the side of the chair when not in useand comparatively inexpensive to manufacture.

Vith the foregoing and other objects in view, the invention consists inthe novel construction, combination and arrangement of parts hereinaftermore specifically described and illustrated in the accompanyingdrawings, wherein is shown the preferred embodiment of the invention.

In describing the invention in detail reference is had to theaccompanying drawings wherein like characters denote corresponding partsthroughout the several views, and in which- Figure 1 is a perspectiveview of a chair attachment in accordance with this invention, showingthe parts dis-assembled. Fig. 2 is an end elevation with the partsassembled, the lower portion thereof broken away. Fig. 3 is a top planview. Fig. 4 is a vertical section. Fig. 5 is a perspective view of achair showing the attachment secured thereto, and, Fig. 6 is a rear viewof the chair showing the arm rest or desk depending at one side of thechair.

Referring to the drawings by reference characters, the chair attachmentcomprises a combined attaching and supporting bracket for the arm restor desk, and which is adapted to be secured to the outer side of one armof the chair and the said bracket consists of a body portion 1 in theform of a flat plate provided at its top with a pair of openings 2,through which are adapted to extend holdfast devices for securing thebody portion 1 to the arm 3 of the chair. The lower part of the bodyportion l terminates in a laterallyextending flange 4 having dependingfrom I one end thereof a pair of apertured lugs 5 for i a purpose to behereinafter referred to. The 1 top of the body portion 1 terminates in afiat plate 6, which is adapted to project over and rest upon the top ofthe chair arm 3 and the said plate 6 is offset at one side, as at 7, soas to form a pair of shoulders 8. The offset portion 7 is formed with akey-hole-shaped opening 9, which is in vertical alinement with akey-hole-shaped opening 10 formed in the flange 4. The plate 6 upon itsupper face at one corner thereof is formed with a stop lug 11.

The chair attachment further comprises a combined swinging and hingesupport for the arm rest or desk, the latter being indicated by thereference character 12 and said support consists of a T-shaped member,the vertical arm of which is indicated by the reference character 13,which constitutes a hinge arm and the horizontal arm by the referencecharacter 14. Said vertical arm 13 is adapted to extend through theopenings 9 and 10 formed in the combined attaching and supportingbracket and the lower end of said arm is formed with a protuberance 15,the function of which is to retain said arm 13 in the bracketthat is tosay, if the arm 13 is insorted through the openings 9 and 10 and given aquarter turn the lug 15 will engage the flange 4 so as to prevent theremoval of said arm 13.

Pivoted to the arm 14 by headed attaching members 16 is a supportingplate 17 which is formed with a depending portion 18 at each side andthrough the said depending portion 18 the attaching members 16 extend.These latter then engage with the arm 14. By such an arrangement theplate 17 is pivoted to the arm 14. The plate 17 is furthermore providedwith a plurality of openings 19 through which are adapted to extendhold-fast devices for securing the arm rest or desk 12 thereto. a

The chair attachment further comprises a connecting member for the lowerportion of the combined attaching and supporting bracket and said memberconsists of an elongated rod 20 which at its upper end is formed with anapertured lug 21 extending between the apertured ears 5 of the flange 4and the said lug 21 is pivotally connected to said ears 5 through themedium of a pivot 22. The rod 20 is formed with a plurality of openings23 through certain of which are adapted to extend hold-fast devices forsecuring the Patented May 21, 1907.

lower portion of said arm to the seat of the chair. By pivoting theupper end of the arm 20 it enables the same to be adjusted so as tocompensate for the width of the chair seat with respect to the arm ofthe chair when the distance between the arms is greater than the widthof the chair as in the majority of cases. The openings 23 formed in thearm 20 compensate for varying distances between the chair arm and theseat so that said arm 20 can be secured to the seat as in some chairsthe chair arms are arranged a greater or less height above the chairseat than in other chairs.

It will be assumed that the arm rest or desk 12 is in the position shownin Fig. 6, and it is desired to move the same to the position shown inFig. 5. The arm rest or desk 12 is then swung upwardly upon the pivot 16and then turned upon the hinge arm 13 so as to position one of theportions 18 of the plate 17 upon the plate 6. The arm rest or desk 12will then be supported in a manner as shown in Fig. 5. To prevent theaccidental swinging around of the arm rest or desk 12 from the chair thelug 11 is adapted to engage the other portion 18 of the plate 6. If itbe desired to position the arm rest or desk 12 in a manner as shown inFig. 6 after it is in the position shown in Fig. 5 it is raised slightlyso as to enable the clearing of the lug 11 by the portions 18, swungupon the hinge arm 13 rearwardly and it is then allowed to turndownwardly upon the pivot 16, consequently assuming the position shownin Fig. 6.
